Management of U.S. Agricultural Lands Differentially Affects Avian Habitat Connectivity

نویسندگان

چکیده

Despite frequently being implicated in species declines, agricultural lands may nonetheless play an important role connecting wildlife populations by serving as movement corridors or stopover sites between areas of high-quality habitat. For many North American bird species, intensification over the past half century has substantially impacted populations, yet recent studies have noted potential for supporting avian biodiversity on through promotion functional connectivity. To support conservation efforts across United States, we used publicly available data from eBird to quantify and map effects agriculture habitat suitability (using random forest models) connectivity (via circuit theory) three focal that experienced agriculture-linked declines range contractions decades: Greater Sage-grouse (Centrocercus urophasianus), Black Duck (Anas rubripes), Bobolink (Dolichonyx oryzivorus). Our analysis drew novel, remotely sensed estimates management intensity practices movement, revealing complex, species-specific relationships value species. Rangelands croplands exhibited relatively high values Bobolink, respectively, mirroring these species’ strong preferences open sagebrush cultivated grasslands. By contrast, migratory was low all cover types.

Is Florida ' s Growth Management Act protecting agricultural lands ?

Florida has experienced more population growth over the past half century than any other state, which has led to some of the most extensive urban development on valuable agricultural lands. To address this and other impacts of sprawl, Florida passed the Growth Management Act (GMA) in 1985, which among other things required local comprehensive planning and that it be consistent with a state plan...

How spatio-temporal habitat connectivity affects amphibian genetic structure

Heterogeneous landscapes and fluctuating environmental conditions can affect species dispersal, population genetics, and genetic structure, yet understanding how biotic and abiotic factors affect population dynamics in a fluctuating environment is critical for species management. We evaluated how spatio-temporal habitat connectivity influences dispersal and genetic structure in a population of ...

Recycling Organic Materials On Agricultural Lands

The recycling of rural and urban organic waste materials onto agricultural land provides a challenge to the producers and end-users who both have a 'duty-of-care' to ensure the method of disposal is managed in a sustainable way. Careful management means that soil and water resources are not contaminated, the agricultural production system remains stable, and land use alternatives remain availab...
